Kilopascal to PSI Converter
Quick Reference Table
Common kilopascal to PSI values for tire pressure and engineering checks.
| kPa | PSI |
|---|---|
| 1 | 0.15 |
| 10 | 1.45 |
| 50 | 7.25 |
| 100 | 14.50 |
| 150 | 21.76 |
| 200 | 29.01 |
| 220 | 31.91 |
| 250 | 36.26 |
| 300 | 43.51 |
| 350 | 50.76 |
| 400 | 58.02 |
| 500 | 72.52 |
| 1000 | 145.04 |
Conversion Steps
To change kilopascal to PSI, multiply kPa by 0.1450377377. Reverse: divide PSI by 0.1450377377 (or multiply by 6.8947572932).
- Example: 15 kPa × 0.1450377377 = 2.18 PSI
- Reverse example: 30 PSI ÷ 0.1450377377 ≈ 206.8 kPa
Popular Conversions
- Tire pressure: 220 kPa = 31.9 PSI (common car)
- 210 kPa = 30.5 PSI (light truck)
- 350 kPa = 50.8 PSI (high-performance)
- Bike: 400-600 kPa = 58-87 PSI
Related Units
PSI connects to bar (1 bar ≈ 14.5 PSI), atm (1 atm ≈ 14.7 PSI), mmHg for vacuum checks.
